63 Thunderbird Electrical Short - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

I recently purchaced a 1963 Thunderbird. There's some sort of electrical short or severe power draw whenever the battery is hooked up. Ignition switch is off and the starter isn't trying to engage (like if the starter solenoid is stuck). I disconnected to voltage regulator but it still does it. Can an alternator cause this? Any other ideas what might cause this?

Thanks,

Ron

Hardtop or Convertible??? Using an ammeter hooked between the negative battery terminal and the negative cable clamp. Gradually remove fuses until the draw is gone. Disconnect the alternator connector too if necessary.

It's a hardtop.

That's a good idea. Thanks!
